BINDING-MACHINE.

Specification of Letters Patent.

Application filed June 16, 1920. Serial No. 389,530.

slides for projectin machines, it is well understood that the's ide usually consists of a glass plate upon which a representation of the image to be projectedis displayed.

With a view of protecting this representation which may be in the nature of a sensitized surface or coloring, it has been customar to superimpose a second cover glass over t e first late, these two members bein subsequeni y attached one to the other.

his attachment has been eifected by utilizing adhesive strips, which were applied so that they enveloped the side edges and the upper and lower. faces, adjacent their side edges of the members thus formed. This stri has thus permitted the forming of a sing e unit of the plate bearing the sensitized or other image carrying surface,

. and the cover glass aside from the fact that any rough edges which may have existed havebeen covered, so that the fingers of the operator were not likely to become cut.

Applying the strips to the side edges of these units has been at best but tedious work, in that it has been necessary to .carefully hold the two glass plates insuperimposed condition, and to apply the adhesive strip with great caution, so that it might envelo all edges of the unit.

A si e from the great amount of time-involved in correctly applyin this tape, has been found-the tape quite often is. positioned in an irregular manner.

With this in mind, I have constructed a binding machine which is moreparticularly adapted for use in connection with the projectlon machines aforedescribed, although the same might readily. be used to bind the edges of any s uare member desired, and by means of which the edges of the plates or units will be quickly and evenly covered with the adhesive bindin element. 1

Referring now more particularly to Figs.

l and 2, it will be seen that my binding .machine conveniently includes a pair of base members 10 which have secured "to their upper faces, and adjacent one of their ends, the longitudinally extending memberll. A second similar member is positioned above the upper faces and adjacent the opposite ends of said base members, ashas been indicated by .the reference numeral 12, it being noted, however, that this lattermember is conveniently provided with any desirable adjusting and retaining means, such as lock pins 13, and thumb screws 14; the former coiiperating with the openings 15 formed in. the upper faces of the base members 10, the latter being mounted upon bolts extending through slots 16 in the member 12 their inner ends being secured to the base members '10 for a purpose hereinafter more fully specified.

From the foregoing it will be-seen that the base portion of the machine provides a longitudinally extending groove or slideway, between the inner edges of the members 11 and 12, the width of which maybe varied by means of the securing and retain- 111%]118613. aforedescribed. v I

slidable' rojecting member rests in the.

groove thus ormed, the said member con-' venientlyincluding a base 17 capable of bemoved through the groove by any suitab e means such as a handle 18 aflixed to its outer end, and being retained therein by.

an desirable type of guides 17 ith a view of limiting the motion of thebase17, a pair of stops 19 are conveniently. associated one with each of these ends, which stops contact with the side edges of the rearmost base member, upon the base reaching its extreme retracted or l The tape projected positions, indicated in dotted and full lines respectively in Figs. 1 and 2.

The slidably projecting member further includes a block 20, which is securely affixed to the base 17. It is to be noted that the block 20 is formed with a cutout portion above "which clips 21 forming a clevis or other suitable securin means extend so that plates 22 may be gripped by means of said block.

With a view of providing supporting means for the slides 22, rails 23 extend throughout the entire length of the base portion, and conveniently overlie the groove formed therein, it being noted that the upper face of the block 20 extends in a. plane substantially similar to the upper edges of the rails 23, which are ailixed to the base of the machine by any suitable means such as supporting legs 24.

It will be understood, by this construction, that the plates 22 may be positioned I upon the inner ends of the rails 23 upon the base 17 being retracted to the position indicated in dotted lines, and that upon the slidable projecting member being moved, that this will result in one of the plate units being moved forward along the rails 23,

The base 17 may new again be retracted, and a second plate broughtto rest upon the rails 23. Upon the base and block 20 again being projected, the last named late unit will be made to slide along the rails 23, and by virtue of the fact, as has been shown in Figs. 1 and 2, that the forward edge of the same will bear against the rear edge of the first mentioned plate, this projection will serve to move the latter also.

Now with a view of taping the edges of the plate units, rolls of tape 25 are provided which rolls may be mounted in any desired manner, as for instance upon brackets 26.

25' passes, subsequent to its withdrawal from the roll between moistening rollers 27 and through guides 28, which serve to cause the same to assume a position transverse to the position originally occupied by the same.

Adjustabl mounted upon the upper faces of the mem ers 11 and 12, such as for instance, by means of eccentrics 29, are rollers 30 having their edges preferably covered with any suitable resilient material, such as soft rubber, it beingnoted that these rollers, as has been clearly shown in Fig. 3, conveniently include a groove portion extending adj acent to the side edges of the units 22;

- 0 the rear of the rollers 30, and extending in the same plane are pulleys 31 ofany desired ty e, which pulleysconveniently include rub er covered faces, and a groove portion at an angle more acute thanth'e groove part of the rollers 30, as has been :clearly shown in Fig. 4. Itis to be noted that the pulleys 31 are rotatably mounted upon standards 32 of any desired type, and

secured to the upper facesof the members 11 and 12 respectively, so that a rolling contact will be afiorded, serving to fold the tape 7 conveniently provided for each of these members, which are positioned one to each 1 side of the rails 23, such pivot including a suitable post 35 adaptedto be engaged by the adjustable retaining member 36. The retaining members 36 each conveniently mount one end of a spring 37, the opposite ends of which bear against the folders, and serve to swing the inner ends of the latter inwardly, stops such as 38 being provided to limit the amount of this swinging motion.

It will now be understood that the slides 22 may be projected through the machine upon thefrails 23 in the manner aforedescribed, and with a view of applying tape to the same, the tape is conveniently passed around each of the rollers 30. It will now 'be understood that upon each slide being projected the tape 25, by virtue of its adhesive qualities will be caused to contact and be applied to the edges of the slides as they pass between these rollers in the manner shown in Fig. 3.

It will be seen that this :action, although serving to apply the tape to the side edges of the slides, will not cause the side edges and adjacent portions to be completely en-. veloped, and with this in view, the pulleys 31 have been provided, which serve, as has been illustrated in' Fig. 4, to bend the tape 25 to assume an enveloping position, and hold the slides down upon the track 23.

A further projection of the slides thus manipulated will cause the side edges of the same to pass into the folders by means of which the tape will be pressed into contact with the faces of the plate unit, this action being further insured by means of the spring fingers 34.

It will be understood that the actions 'aforedescribed will serve to produce the any danger of a loosening of the same is precluded.

Referring now more pa-rticularly to Fig. 5 it will be seen that'this roller group pre erably includes two pairs of vertically, extending rollers 39, rotatably secured to the inner side edges of the members 11 and 12 respectively, it being noted thatthese rollers over-lie and under-lie the plane occupied be firmly pressed-into intimate contact with I the same upon the slide passing through the roller group aforedescribed, so that any danger of the same becoming removed is precluded.

From the foregoing it will be understood that I have constructed a binding machine which shall be capable of applyin tape to the longitudinal edges of slides. ow with a view of applying tape to the side edges of the same it will readily be appreciated that any desirable number of plate units may be projected through the machine and subsequently separated one from the other. The member 12 is now moved outwardly by virtue of the adjusting and securing mem bers supplied for this purpose, so that a groove of greater width is presented, it belng noted that one set of rollers 30, roller groups 39 and 4:0, and one of the pulleys 31 will, by virtue of the fact that they are carried by this member, move with the same.

The plates may now be rested one at a time upon the forward ends of the rails 23, and projected through the machine by means of which tape will be applied to the side edges of these plate groups, sothat a ,series of completely taped plates are presented at the rear or delivery end of the machine.

From the foregoing it will be appreciated that I have constructed a binding machine by means of which tape may be ap lied to both the longitudinal and side e ges of plates or other square plate members'to be bound, which tape will be speedily and uniformly positioned in the proper manner.

Obviously numerous modifications of structure might readily be resorted to without in the least departing from the spirit of my invention.
